This invention relates to and has fora main object the provision of improved means for attaching the end of a motion picture film to prevent the unwinding thereof when the same is mounted on a reel.

An object is to provide an integrally formed spring metal clip having a body portion adapted to be transversely disposed over a motion picture film with projections formed thereon for registration and engage ment with the perforations of a film, and end portions adapted to overlie the edges of the film in such a manner that the said projections and end portions will frictionally engage the film so as to prevent accidental dis placement of the clips and the unwinding of the film.

In the accompanying drawings I have shown several modified forms of device for attaining the above named objects, in which Fig. 1 is atop plan view of a clip.

Fig. 2 is a side elevation'of the same.

Figs. 3 and 4 are side elevations showing modified forms of the device.

Fig. 5 is an edge view of a film wound into a plurality of convolutions with my improved clip attached thereto for preventing the unwinding of the film.

Fig. 6 is a top plan view ofthe same.

Fig. 7 is a transverse section of the same on line 77 of Fig. 6.

Fig. 8 is a bottom plan view of the form of clip shown in Fig. 7

The preferred form of device is shown in Figs. 5 to 8 inclusive, and embodies an integrally formed clip A with an elongated body A1 bent downwardly at A2, A2 and thence outwardly at A3, A3. The body A1 is adapted to be transversely disposed across a roll or reel of film F, and the ends depend downwardly over the edges of said film, as shown in Fig. 7. 7

Near the ends of the clip I provide one or more projections A4, A4 which are formed by q indenting the upper side of the clip A. The

projections A4 are transversely spaced apart to conform to the spacing of the film perforations F1, F1, etc., and where more than one of the projections A4 is provided the, projections are spaced apart transversely of the clip to correspond to the longitudinal spacing I of the perforations F1.

As shown in Figs; 1 and 2, the body A1 of the clip may be recessed at the sides, as at A5, and the end portions of the clip may be formedsomewhat difi erentlyyas in Fig. 2, one of the portions A3 being omitted fromthe adjacent portion A2, or, as shown in Fig. 3, the portions A3 may be omitted from both ends of the clip.

Another form of device is shown in Fig. i, which is similar to'the form shown in Figs. 5 to 8 inclusive, except that the body portion A1 is provided with an upwardly bent centralportion A6 which may serve as a means for gripping and holding the clip when the same is being attached to or detached from a film. Heretofore'the outer ends of the films F, when carried on ordinary motion picture reels, have been variously attached to the reel so as to prevent the unwinding of the film.

It is the purpose of my improved clip, as shown in Fig. 5, to apply the clip to the outermost convolution of a roll of film on a reel at a point near the outer end of the film with the projections A4 seated in the perforations F1 in the film and the end portions A3 of the clip overlying and frictionally engaging the edges of the film so that the film may not be accidentally unwound, and thus possibly injured during ordinary use.

Frequently in the production of motion picture films relatively short strips or" film are made of different scenes which are not rolled on the usual motion picture reels, and my clip is admirably adapted for attachment to such a piece of film for preventing the un-. winding of the same when it is wound compactly in a roll.

It will be quite obvious that the clip shown and described herein may be made in variable widths and the body A1 may beformed to suit varying conditions of use, and the clip may be otherwise modified within the scope of the appended claims without departing from the spirit of my invention.

What I claim is:

1. A fastening device for a coil of motion picture film comprising a clip formed with a flat body member and end members, said body member being constructed and arranged to extend transversely over the outer coiled portion of the film, and said end members being adapted to frictionally engage the 5 sides of the coil of film, and projections on said body member adapted to project inwardly into the film perforations.

2. A fastening device fora coil of motion picture film comprising a clip formed with a fiat body member. and end members, said body member being constructed and arranged to extend transversely over the outer coiled port-ion of the film, and said end members being adapted to frictionallyengage the sides of the coil of film, projections on said body member adapted to project inwardly into the film perforations, and said body member being bentoutwardly between the projections at the ends of said body member 2U in'the form of a handle.
